Abstract: A clipping processor clips a two-dimensional subject figure against a clip region by first scan-converting the clip region and storing it as endpoint data of clip segments, then scan-converting the subject figure, clipping the subject segments a scan line at a time against each of the clip segments on that scan line, and converting the clipped segments to pixel data. The clipping process is thus efficiently combined with the standard processes of scan conversion and pixel generation, producing clipped data that are ready for raster output. The clipping process is moreover performable by simple, rapid DDA algorithms, even when the clip region is bounded by high-order curves such as Bezier curves and spline curves, and can easily be implemented in high-speed, dedicated hardware.

Abstract: Apparatus for detecting line-over defects at the finish of a glassware container. A bifurcated fiber optic bundle (30) includes sender (31) and receiver (33) fiber branches; one of the branches terminates at a modu­lated visible red high intensity LED light source, the other at a photosensor. The non-bifurcated, probe end (46) of the fiber optic cable terminates in a rectangular pattern of sending and receiving fibers in a random mix. The probe end of the fiber optic bundle is positioned directly over the container finish (10) and pointed straight down. An intervening lens assembly (43) produces a focused 1:1 image of the rectangular pattern at the bottle finish with the long axis of the rectangle oriented radially across the finish. An electronic assembly modulates the LED, demodulates the photodetector output, and de­tects sharp reductions in the intensity of light reflected back to the receiver fibers, indicative of line-over defects.

Abstract: An automated process and device for testing both C.W. and swept output signal modulation of a system or unit under test. The invention conditions the output signals to be compatible for measurement, measures incremental cycle periods of the signals using a continuous time counter, converts raw signal data into formatted tables, calculates prescribed parameters relating to the signals, aligns the calculated prescribed parameters relating to the signals, computes incremental signal frequencies from the incremental cycle periods as measured, substarts the incremental signal frequencies from the predicted signal frequencies to form a frequency residual model, constructs a curve using the incremental signal frequencies, and displays the curve. A prediction model is created and used to predict expected results. The prediction model defines ideal behavior of both C.W. and swept signals from a unit under test. The ideal behavior data is subtracted from the actual data, leaving a coarse representation of non-linearities. A combi­nation of digital filtering, least squares curve fitting and the Choelsky method for solving simultaneous equations is used to refine coarse data into a frequency vs. time continuous curve or for other uses by the unit under test. The invention can be used for integrated circuit testing in manufacturing and incoming inspection for all types of fixed oscillators, all types of voltage controlled oscillators, and amplitude modulation and frequency modulation heterodyning chips, and instrument and module testing   for manufacturing, incoming inspection, field test and diagnostics for function generators, sweep generators, oscillators and synthesizers.
